,13 Claims. (Cl. S12-38) Towel cabinets adapted for delivering a wipinglength of clean towel to a user, are usually provided with a stop deviceto be moved to a release position by the towel user preparatory todelivery of the towel web and adapted to check positively the feed ofthe towel when a certain predetermined or suitable wiping length oi theweb has been delivered.

It is" desirable" of course inthe interests of economy or towel use, toprevent theuser from delivery a greater length of towel than isnecessary for his purpose and thereby prevent waste of thev clean weband prolong the time during which a web of certain length may be used.It

the release lever, may continue the pressure of his finger thereon andoperate the towel feed continuously, thereby withdrawn from the cabineta very much longer length of web than is relquired for his purpose.

The primary object of our invention therefore is to provide means inconnection with a towel feed controlling device which will positivelyprevent the towel user from obtaining more than a predetermined wipinglength of the web with one operation of the releasing lever.

. A further object is to provide a eed stop mechanism that is adaptedparticularly for use in .ccnnection `with a towel cabinetwherein ancuter porting the operating mechanism of the cabinet is movableforwardly to a position convenient for loading the cabinet andstretching the web of the towel supply upwardly in the rear of the rmovable section to a take up roll. p

A further object is tc provide a feed control mechanisml oi simple,inexpensive construction which can be readily applied to a towelcabinet, and capable of withstanding rtheuse of inexperienced persons orthose who may be maliciouslyinclined.

Other objects of the Ainvention will appear from Y the followingdetailed description. Y 4 The invention consists generally of variousconstructions and combinations, all as hereinaiter described, andparticularly pointed out in the claims.

In the drawings, 2 represents a towel cabinet having an open iront and asuitable door 3 therefor. i is an inner section pivotally supported at 5and adapted to swing outwardly through the open front of the cabinet ierconvenience in loading the cabinet with clean towel and normally held inits positionwithin the cabinet by a locking device 6. The vlower portionof the inner section vpreferably has a suitable supportior a clean towelsupply 7 above which is a feed roll 8 having asuitable drivingconnection witha similar take up roll 9. A soiled towel roll l0 isprovided with its convolutions ci soiled towel thereon adapted toContact with thev roll 9 and be revolved thereby to wind up the soiledtowel. VA tension devicell is preferably positioned to engage the'soiledtowel and smooth out the wrinkles therein as itpasses to the taire uproll 10. A pinch roll 12 is preferably provided in slots 1.3 near thefeed roll 8 and the web clean towel is stretched upwardly from thesupplyover the pinch roll and thence downwardly through the bottom oi the,cabinet and up in the rear of the support of the clean towel to thetaire up yroll 10.

The invention in this application relates to the mechanism means ofwhich the operation of the roll 8 and the iced of the clean towel iscontrolled, and the adaptation of this mechanism to a cabinet having amovable inner section, and we will now proceed to describe thismechanism in detail.

VThe roll, SY has Ya shoulder 14 thereon and a curved cam surface l5'. Adog 16 is pivoted lat 17 and is provided with a stop 18 normally in thepath of the `shfmider le to lockithe feed roll against revolution.l Thelower end of the dog 16 Y has a curved edge lu to engage thecorresponding.` edgeoi a guide plate 2c that is secured to Y the casing.YA slide 2l has a slot 22 therein to receive a pin whereon said slide isadapted to move. The dog 15 has a shoulder 24 in position tobe engagedbya flange 25h11 the plate 21.y A

lever composed preferably of sections 26 and 26 is pivoted intermediateto its ends at 27 and section 26 is adapted to engage a ange 28 on theplate 21. A housing 27 preferably encloses lever section 26. lyconnected with the lever section and eX- tends outside of the casing andhas a finger pieceH 30 that is adapted to be grasped by the user of thetowel for the purpose of manipulating the lever and releasing the feedroll. Inward movement of this member 29 will osoillate the leversections 26 and 26 from the position shown in Figure 3 to that shown inFigure 4 and at the same time ie plate 21 will be actuated to oscillatethe dog 16 and move the stop 18 out of the path of the shoulder 14 sothat the feed roll will then be released and the user by pulling on theweb may obtain a suitable length of towel for wiping purposes.

The end of the feed roll is vpreferably provided with a pin 31 which inthe latter part of the revolution of the roll will engage the edge 32 ofthe plate 21 and disengage the ange 25 from the shoulder 24, the plate21 being guided in this movement by means of a tongue 33 and a plate 34under which the said tongue 33 is Y This movement of the plate 21releases the dog 16 and the shoulder 14 now contacts with the projectingedge 35 of the dog as the feed roll revolves and swings the dog 16 onits pivot from the position shown in Figure 4 tothe point illustrated inFigure 6, where the stop 18 will be positioned in the path of theshoulder 14 to positively check the revolution of the feed roll andlstop the feed of the towel. This will take place even though the user ofthe towel may hold the member 29 in its release position. The pin 31will engage and move the slide out of engagement with the dog and thestop or shoulder on the roll will then posi- .tively engage the dog andmove it to its locking position regardless of what the user may havedone to the release leverand its operating member. f

To obtain a wiping length of towel, the user will press the iinger pieceat the` end-of the member 29, thereby actuating the slide and causing itto engage the shoulder on the locking dog to swing it from the lockingposition lin Figure 3 to the release position of Figure 4. The feed rollmay then be revolved by pull on the towel web, and when it has nearlycompleted its revolution, the pin 31 will engage the'edgeof the slideand force it out of its locking engagement with the dog, which is thenfree to drop'back to its locking position Yby gravity, but this movementis preferably insured by the engagement of l the shoulder on the feedroll with the projection on the dog, such engagement forcing the dogfrom its release back to its locking position where its stop will be inthe path of the shoulder 14 to positively arrest movement of the feedroll and delivery of the towel, and this will take place even though theuser may have kept his ringer on Y the reciprocating member that isconnected to the release lever. 4

` The stop device is adapted particularly for a towel cabinet having aninner movable section capable of adjustment as shown in Figure 8 forconvenience in removing the soiled towel and arranging the supply ofclean towel in the cabi- The mechanism of the stop device is soarranged, a portion being mounted on the outer section so that the innersection of the cabinet A reciprocating member 29 is pivotaldelivery ofthe towel.

may be moved outwardly to its loading position temporarily separatingthe stop device from its operating lever and rendering this deviceinoperative at this time.

When the inner section and the stop device is returned to its normalworking position, the release lever will again be in position to performits function when the towel user manipulates the ringer piece on theoutside of the cabinet. IIhe normal working position of the releaselever is indicated in Figure 2 where the movable inner section is shownin its normal position within the cabinet.

In VFigure 8, this section is shown tilted forwardly through the openingin the front of the cab-inet and that portion of the stop mechanism thatis mounted on the inner section will of course move forwardly with thissection while the release lever and the operating member connectedtherewith mounted on the stationary outer wall of the cabinet willremain in its normal position and not in any way interfere with theforward movement of the inner section. As soon as the loading operationis completed, the inner section is returned to its normal position andthereupon the element of the mechanism carried by the movable sectionwill again be in the path of the release lever ready to be moved to itsrelease position and disengage the locking dog from the cam on the rollwhenever the operating member connected with the release lever ismanipulated by the user of the towel. We are thus able to employ a stopmechanism for the rolls in connection with a cabinet having the innermovable section without in any way interfering with the convenientmoving of this section toits load-- ing position, the elements of thelocking mechanism being temporarily separated and then returned to theirnormal working position without any attention on the part of the personloading the cabinet.

In various ways the details of construction herein shown and describedmay be modied and still be within the scopejof my invention.
